What is sd ext? How do I know if I have it and if I dont hire do I get it

 

[cmizzle]

now im not 100% on this but im pretty sure it means you sd card is formatted in FAT32 instead of ext2,ext3,or ext4 . when you make a partition formatted your partition to one of those (im not 100% which one)

hope this is helpful

sd-ext is a second partition of the sd card, by default the sd card has one partition

the sd-ext can be used by programs like link2sd or apps2sd to store some of your apps on that second partition, and free up some space in your internal memory

if you did not parition the sd card with ClockWorkMod or some computer software, you dont have it

an easy way to get an sd-ext partition is to use ClockWorkMod, and partition the card in the advanced menu

BUT MAKE SURE YOU BACK UP THE FILES ON YOUR SD CARD FIRST

When you partition your card in CWM it erases the SD card

Swap is to linux what virtual memory is to windows.
the problem is on android it manages memory very well on its own it was made to not need swap but if it has it available it will use it. Swap is memory items written to the physical disk, Your sd card and that disk is much much slower then memory. So the way I read it if you have swap available android will keep things in memory and the older it will write to swap, thats good in theory but practical if it did not have swap it would just close those that are not needed, And say you decide you want to go back to that program it actually takes android longer to reactivate the swap information then it does to reopen the program from its closed state.

yes but if android shuts a program your unsaved work goes away sometimes. in swap file, does the program remain in the open state? if so, id rather have swap memory than rely on android management. do you know, or can u test, if programs remain open if they are moved to android swap file?

I believe android saves unsaved work, but I dont know and no I can not test it, I dont use swap and I am no longer using the prevail.

Sd ext beats swap hands down
